Jquery can't get my head around this

Question

The alert(i) onclick bind line is run on 3 divs, but all of them when clicked alert the last set value of i. I hope what I\'m trying to do makes s

Answer 1

When you're iterating in the for loop, you're essentially given the address to i, if you use it within the for loop at that very moment, it will be the value expected, however if you use it later (such as in a click event) it will point to the final incremented value of 3. To get the desired affect you can create an anonymous function, like so

for (var i = 0; i < self.bars[BarsIndex].markers.length; i++) (function(i) {

    // Add click event
    $("#bmi-" + self.containerId + "-" + i).bind('click', function() {
        alert(i);
    });
})(i)
